Subject: [PATCH v3 1/5] xfs: do the ASSERT for the arguments O_{u,g,p}dqpp
Date: Wed, 7 Oct 2020 22:51:08 +0800 [thread overview]
Message-ID: <1602082272-20242-2-git-send-email-kaixuxia@tencent.com> (raw)
In-Reply-To: <1602082272-20242-1-git-send-email-kaixuxia@tencent.com>
From: Kaixu Xia <kaixuxia@tencent.com>
If we pass in XFS_QMOPT_{U,G,P}QUOTA flags and different uid/gid/prid
than them currently associated with the inode, the arguments
O_{u,g,p}dqpp shouldn't be NULL, so add the ASSERT for them.
